摘　　要：利用CMOS图像传感器与DSP芯片构成一个高速动态成像系统。由DSP电路驱动CMOS芯片并通过片上AD变换后输出数字信号并即时进行处理。利用这个系统进行了单帧与连续帧的图像采样实验,获得了比较理想的结果。证明了采样频率越高,其对于运动物体的测量数据就越准确。整个系统结构简单,性能可靠,可以灵活地改变三种获取图像的模式,便于对图像信息进行数字化处理。An imaging system with a CMOS image sensor and a DSP chip are built to get high-speed dynamic image.The on-chip ADC affords the digital image signals under the driver of DSP chip.Some single-frame and continuous frames imaging experiments are carried out with this system,which proves that the higher sample frequency leads to more accurate measurement results.We can optionally choose one of the three modes of the CMOS operation,and it is convenient for us to progress the digital image
